Is Section 21956 of the California Vehicle Code sufficient to instruct police officers that pedestrians can legally walk in the roadway?

^5. We note that the court in People v. Cox, supra, 168 Cal.App.4th 702, held that the officers in that case "failed to comprehend the California Vehicle Code, something they are reasonably expected to know. (See People v. McNeil [(2002) supra,] 96 Cal.App.4th [1302,] 1309.) Section 21956, subdivision (a) was enacted over 40 years ago. [Citation.] This is more than enough time for any California police department to analyze and properly instruct its officers that pedestrians can legally walk in the roadway in a business or residential district." (People v. Cox, supra, 168 Cal.App.4th at pp. 710-711 [fn. omitted].)
